MEANS FORUNITING DOUBLE GUN-BARRELS.

SPECIFICATION forming part of Letters Patent No. 246,195, dated August23, 1881. Application filed April 23, 1881. (No model.)

To all whom it may concern:

Beit known that I, HENRI PIEPER, of the city ot' Liege, in the Kingdomof Belgium, have inyen tedan Improvement in the Mode of Unit- 'ing theBarrels of Double-Barreled Guns; and

I do hereby declare that the following is a true and clear specificationthereof.

In the accompanying drawings, in which similar letters indicatecorresponding parts, Figure l is a plan View of the united barrels; Fig.2,`a side View ot' them and a cut through the breech piece and thedouble link in an axial plane ot' 011e barrel; Fig. 3, an end view; Fig.4, a cross-section of Fig. l in the line A B; Fig. 5, a cross-section ofFig. l in the line C D; Fig.6,`acrosssection of Fig.l in the line E F;Fig. 7, a View and partial section of the breech-piece.

Through the breech-piece a are bored two conical holes for receiving thetwo barrels b b, which are turned or shaped conical-that is to say,thicker on their breech ends than on their niuzzles-so as to itaccurately in the said conical holes ot' the breech-piece. The directionof these conical holes is such that when the barrels b b are introducedinto the holes they` meet or touch each other at their muzzle ends, atwhich extremity they are unitedby their insertion into the double linkc, which -litsover the reduced or offset parts ofthe barrel ends on'themuzzle. On the under side of the barrels the breech piece a has theextension c', running up the barrels a suitable ordesired distance. Nearthe upper end it has the plug @extending up between the barrels andforming a point of attachment for the screw in upper strip. This servesto steady audhold the barrels, and keeps them at just the right distanceapart. The open space between the two barrels b b, from the breech endto the double link @,is closed throughout its entire length by means ot'the two narrow strips d and c. The wider of these strips, d, is placedabove the barrels Z1, forming the prolongation of the strip i of thebreech-piece n, to which it is attached by the two screws fg, the otherend of it being fastened to the double link c by the screw h. Thenarrower and smaller strip, c, is placed below the barrels a, andfastened there in a similar or in any convenient manner. Finally, theso-pre'pared barrels b, breech-piece a., double link c, and strips d eare brazed or soldered together.

It must be understood that the breech-piece n can be used, incombination with the double link c, on double-barrcled guns, or only oneof these devices may be used, the other or its equivalent then beingconstructed in another way.

I claiml 1. The breech piece described, having the conical bores forreceiving the barrels, the extension a', and plug a2, substantially asset forth.

2. The double gun-barrelandjoining means described, consisting of thebarrels b b, breechpiece n a a2, strips d e,and link c, substantially asset forth.

This specication signed by me this 11th day of March, 1881..
